ACETYLENE-GAS 6 EN ERATO R.

SPECIFICATION forming part of Letters Patent No. 627,747, dated June 27,1899.

' Application filed October 10,1898. Serial No- 693,139. [No model.)

To all whom, it may concern.-

Be it known that I, KARL GUSTAF GUSTAFS- SON, mechanical engineer, of 4Sibyllegatan, Stockholm, Sweden, have invented an Improvement inAcetylene-Gas Generators; and I do hereby declare the nature of myinvention and in what manner the same is to be performed to beparticularly described and ascertained in and by the followingstatement.

In apparatus for producing acetylene gas where the carbid is allowed todrop into the gas-generator through the free surface of the liquid it isnecessary in order to prevent the generation of gas commencing beforethe carbid has had time to sink to the place Where the generation of gasis intended to take place to let the carbid pass through a sufficientlydeep layer of aliquid-s-uch as oil, for instancewhich floats on thewater and does not generate gas with the carbid and, moreover, does notretard the generation of gas too much on the introduction of the carbidin the water. As, however, the bubbles of gas formed cause considerabledisturbance of the liquid as they rise to the surface, an emulsion ofthe oil and water is soon formed which is unable to protect the freshcarbid fed in from generating gas prematurely, said gas in this casegaining access to the room or other space wherein the gas apparatus islocated.

The object of the present invention is to so arrange apparatus of thekind referred to that the above-mentioned inconveniences are avoided.

In the accompanying drawing is shown a longitudinal vertical section ofthe gas-generating chamber proper of an acetylene-gas apparatus orgas-generator arranged in accordance with the present invention.

a is the water and oil reservoir, and b the feed-passage for the carbidwhich falls alon g an inclined plane d into the water which is coveredby a layer of oil '0. The improved arrangement consists in placing inthe gasgenerating chamber a a chimney or flue g, the lower end of whichreaches below the surface of the water, while its upper end projectssomewhat above the layer of oil. The said flue or chimney is closed atthe bottom except in one place, (at h,) where the carbid descendingalong the inclined plane can enter into it. Moreover, by means of apartition 2' there is formed in the said flue a passage 70, the upperend of which terminates about on a level with the surface of the layerof oil, while its lower end terminates in the water at the bot tom ofthe flue. can be replaced by a special pipe communi eating at the topwith the flue 9.

When the carbid is fed into the apparatus, it slides at once along theinclined bottom into the lower part of the leg g, and the generation ofgas commences as soon as the water has had time to penetrate through theadhering film of oil, when the rising bubbles of gas communicate anascending motion to the body of water in the flue g. Should there be anyoil floating on the water in the flue g, this oil is forced to accompanythe current of water which flows down over the edge of the partition '5through the passage is and finally issues at the bottom of the flue,where the oil rises to the layer of oil situated above, while the wateragain flows into the line g through the aperture 72.. By this means acirculation of the water is brought about, which results in that, on theone hand, the flue g, as arule, always remains filled with pure wateronly, not with water and oil, and, on the other hand, that bubbles ofgas cannot find their way out through the aperture h. Consequently inthe generation of gas no emulsion of the oil and water is formed, theoil remaining unaltered.

The supplemental bottom of the leg g is hinged, as at m, and is providedwith a suitable operating-rod extending up through the top of thecasing, the lower end of theopcrating-rod being linked to the free endof the cover to permit its being dropped into the po sition shown indotted lines.

The lime formed by the chemical reaction accompanies the circulatingwater and settles at the bottom of the apparatus, whence it can beremoved by means of a cock Z.

. Finallyit should be added that the passage k can be omittedaltogether, in which case the-water thrown up-over the upper edge .ofthe flue g is allowed to sink through the layer of oil outside of theflue.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. An acetylene-gas apparatus comprising Evidently thesaid passage a closed chamber adapted to contain water and oil, avertical leg within said chamber depending below the water-line andhaving two compartments or passages, said compartments or passagescommunicating with each other slightly above the oil-level, and aninclined movable supplemental bottom closing the lower end of one of thecompartments and serving to direct the carbid through an opening in theleg below the water-line into said closed compartment, and means foroperating said movable bottom, substantially as described.

2. An acetylene-gas apparatus comprising a closed chamber adapted tocontain oil and water, a vertical leg provided with a bottom within saidchamber and depending from above the oil-surface below the water-line,said leg below the water-line having an opening h for the carbid fedinto the leg, and a 20 KARL GUSTAF GUSTAFSSON.
